Orality and Literacy

Ong systematized what McLuhan had intuited: that the shift from oral to literate culture was not merely a change in technology but a transformation in the structure of consciousness. He catalogued the cognitive characteristics of primary oral cultures — aggregative rather than analytic, redundant, conservative, participatory — and showed how writing made possible abstraction, categorization, and the separation of the knower from the known. The book is compact, clearly argued, and avoids McLuhan's oracular style while extending his core insight with anthropological and linguistic evidence. It is essential for thinking about what any new medium does to thought, because it establishes the baseline: what thinking was like before literacy reshaped it. Anyone working on digital products who wonders what screens are doing to cognition should start here, with what print did first.
